[Tex/LaTex] Multiple citations in a single year using biblatex

biblatex

My biblatex preamble is like this:

\usepackage[bibstyle=authoryear,
citestyle=authoryear, 
firstinits=true, 
maxbibnames=5,
minbibnames=3, 
maxcitenames=2, 
sorting=nyt, 
url=false, 
isbn=false, 
eprint=false, 
doi=false, 
dashed=false, 
natbib=true]{biblatex}

When I cite two papers by the same author in the same year (\citet{Einstein1905a, Einstein1905b}), they appear as follows:

Einstein (1905a); Einstein (1905b)

Instead, I would like for them to appear as:

Einstein (1905a,b).

How can I accomplish this?

biblatex doesn't feature a built-in style which compresses only papers by the same author and in the same year. If compressing of same author/different year is fine with you, simply use the authoryear-comp style.

\documentclass{article}
\usepackage{filecontents}
\usepackage[style=authoryear-comp,natbib]{biblatex}
\addbibresource{\jobname.bib}
\begin{filecontents}{\jobname.bib}
@article{one,
author = "Last, First",
title = {Title},
journal = {A Journal},
year = {2011},
}  
@article{two,
author = "Last, First",
title = {Title},
journal = {B Journal},
year = {2012},
}  
@article{three,
author = "Surname, Given",
title = {Title},
journal = {C Journal},
year = {2013},
}  
@article{four,
author = "Surname, Given",
title = {Title},
Journal = {D Journal},
year = {2013},
}  
\end{filecontents}

\begin{document}
\citet{one,two,three,four}
\printbibliography
\end{document}

[Tex/LaTex] Multiple citations with pages using BibLaTeX

You can use the multicite version of \cite:

\cites{ref1}[2]{ref2}[3]{ref3}[4]{ref4}

This will roughly give the following output:

<label1>; <label2>, p. 2; <label3>, p. 3; <label4>, p. 4

In general \cites takes arguments of the form

\cites(<multipre>)(<multipost>)[<pre>][<post>]{key}[<pre>][<post>]{key}...

where the first two arguments (<multipre>)(<multipost>) serve as an "overall" pre- and post-notes and the remaining arguments can be repeated as necessary. Citations are printed in the order given with compressed citation labels depending on the style.

For further details refer to material on "qualified citation lists" in the biblatex manual.

[Tex/LaTex] Citing (author, journalabbr., year) needed

First thing to do is to add a field for the journal abbreviation to the article entrytype, journalabbr in the MWE. Therefore you need to declare a datamodel (an extra file; in the MWE I've used filecontents to simulate that) and you have to tell biblatex/biber to use it in the package options.

Then you have to modify the cite command, so it fits your needs. \citep from the authoryear-style (your citestyle) uses the \cite command. There you just have to add a switch, which checks if the field journalabbr is empty or not, and prints it out or not.

Last but not least you have to add the abbreviation fields to the entries.

MWE:

\begin{filecontents}{min.bib}
@article{boisson2003unexpected,
  title={Unexpected protein families including cell defense components feature in the N-myristoylome of a higher eukaryote},
  author={Boisson, B. and Giglione, Carmela and Meinnel, Thierry},
  journal={Journal of Biological Chemistry},
  journalabbr={JBC},
  year={2003},
  publisher={ASBMB}
}
\end{filecontents}

\begin{filecontents}{authorjabbryear.dbx}
\ProvidesFile{authorjabbryear.dbx}
\DeclareDatamodelFields[type=field,datatype=literal]{journalabbr}
\DeclareDatamodelEntryfields[article]{journalabbr}
\end{filecontents}

\documentclass[fontsize=11pt, paper=a4, ngerman, DIV=calc]{scrartcl}
\usepackage[scaled]{helvet}
\renewcommand*\familydefault{\sfdefault}

] {biblatex}

\DefineBibliographyStrings{ngerman}{ andothers = {{et\,al\adddot}} }

\renewbibmacro*{cite}{%from authoryear.cbx
  \iffieldundef{shorthand}
    {\ifthenelse{\ifnameundef{labelname}\OR\iffieldundef{labelyear}}
       {\usebibmacro{cite:label}%

     \iffieldundef{journalabbr}{}{%

        \setunit{\nameyeardelim}%
        }%
     \usebibmacro{cite:labelyear+extrayear}}
    {\usebibmacro{cite:shorthand}}}

\addbibresource{min.bib}

\begin{document}

\citep{boisson2003unexpected} 

How it should look like: 

(Boisson et al., JBC, 2003)

\printbibliography

\end{document}
